Arrange the following steps in the enforcement process of the Sherman Antitrust Act from initiation to resolution: A) Investigation by the Federal Trade Commission, B) Court ruling on the case, C) Filing of a lawsuit against the offending entity, D) Assessment of market impact and consumer harm.

The first step is to assess the market impact and consumer harm, which tells the authorities whether a problem exists. Next, the Federal Trade Commission investigates the alleged conduct to gather evidence. If the evidence shows a violation, a lawsuit is filed against the offending entity. Finally, the case goes to court, where a ruling decides whether the conduct violates the Sherman Antitrust Act. For example, if a company is suspected of price‑fixing, investigators first look at how prices affect consumers, then investigate, sue, and the court makes the final decision.
